PAPER BOX AND PROGESS'OF MAKING THE SAME.

Application filed August 2, 1926. serial lq o'. 126,581.

This invention relates to a new form of paper box principally adaptedfor packing vegetables but which is of general value in packing variousmaterials. The paper box of this application is particularly adaptable.

to the packing of tomatoes.

The object of my invention is to provide a box preferably of square orrectangular cross section in which the tomatoes do not come into contactwith the sides, but in which there are held within a liner which.

in the case of a squarejbox is preferably circular in form, so that theliner proper Wlll touch the interior of the box at four points 5' in themiddle of the sides thereof and will.

and bottom of the box, and by using thev square exterior the box willstand rough handling and shipping, while at the same time, the roundinterior will reduce the tend- 3 It formerly was customary to packreadily crushable vegetables, such as.tomatoes, in either a boxconstructed of wood made by cutting a regular tomato crate in'half byrunning it through a sawing machine or in a large box made of corrugatedpaper. The use of a Wooden box was undesirable because the readilycrushable vegetable along the side and top of the boxwould'become'bruised and valueless because of the pressure of the boxupon the contents, and

u moreover since the box used was a large box it was found necessary toplace three small wooden containers called tills within it, in

I which the tomatoes were placed, and since these tills were not in afixed position they frequently in handling the box would slide againsteach other, crushing and bruising the tomatoes.

A'wooden box of this character was very expensive, due to the fact thata special sawing machine was necessary to cut the box .into the propersize and it was also necessary to, line the inside of the box with papersheets to prevent the tomatoes from coming ency of the tomatoes to crushin the corners.

of these things increasing the cost of matcrials and labor. This type ofbox was not strong enough to bear much pressure and often the entirecontents of a'box were found to have become crushed because of theweight of other boxes placed upon it..

The other alternative, the large corrugated paper box, is alsoundesirable for many of the above reasons andfor the further reason thatit is necessary-to place tills within it which slide about within thebox crushing the tomatoes. This corrugated paper package has a largeunprotected top whlch often buckles in in the center when anyconsiderable weight is placed upon it. This boxas well as the wooden oneis de- 7 signed to hold about from20 to 25 pounds of tomatoes and thetomatoes were often crushedby their own weight. In this box it was alsooften necessary to wrap each tomato in an individual tissue paperwrapping to prevent its coming into contact with the top and sides ofthe box, thus bruising and crushing the tomatoes.

Both of these boxes because of their large size were unwieldy and hardto handle and 8 stow into cars when shipping, and lnol'cowr the storageof these boxes before the regretables were packed into them occupied agreat deal of space.

In my box containing an integral liner the vegetables will all becontained within a liner and since the box can be made of small size veI readily it is unnecessary to place tills wit iin it, thus obviating anexpensive and at the same time a very destructive feature of the oldtypes of box, and moreover it is not necessary to wrap individualtomatoes in a tissue wrapper. Due to the presence of a liner the top andbottom of the box are much more able to withstand 1 outside pressureand-there is much less pos-. sibility of a box being crushed. Noexpensive sawing machines are required nor any other expensive machineryin making the box of this application.

In this manner I am also enabled to put in staggered ventilating holeswhich will admit air to the interior of the box, and will at the sametime prevent direct introduction of air currents or other materialswhich are 110 be of cardboard,- corrugated paper or other papermaterial. when using corrugated paper 'to use corrugated double-facedboard that is smooth faced on both sides, or to use only single facedboard the smooth faced side being on the exterior of the box.

In making my box if I use the same material for both the exterior andthe liner I can stamp it out in one piece in such a manner,

that by folding the box it can readily be made up for packing thevegetables and at the same time is very stamping or cutting machines andeasily stored.

In case the exterior is made of different material from the liner, Iwould make my exterior by stamping out paper of desired paper materialand also make. my interior by stamping the desired paper, material andthen connect the exterior and liner'by means of staples or wire so thatthey will to ether form the same stamping as if the who e had beenstamped from a piece of the same material, and in this way theconveniences of storage and the'ready prcparing'of boxes by folding foruse is achieved. It is very desirable to have the liner of one piece sothat there will be a continuous circular or oval surface within the boxwhen it is used with as few breaks in the surface as possible.

My invention is mademore clear by the drawing which is described asfollows:

In the drawing, Figs. 1 and 3 represent pieces of paper which have beenstamped or cut out from cardboard, corrugated paper or other suitablematerial which when folded will give a box of the desiredcharacteristics.

The manner in which the box looks when the folding is completed isillustrated in Fig. 2. In Fig.1 parts 5, 6, 7 and 8 represent the sidesof the box; a represents the scoring lines along which the paper willfold. 1, 2, 3 and 4 represent parts which can be folded over to form thetop of the box and 1 '2 3 and 4 represent parts which can be folded overto form the bottom of the box. In Fig. 1 the part9 is cut out or stampedout integrally with the remaining portion. 10 represents air-holes inthe sides of the box. These may be decreased in number or eliminated ifso desired. 10 re resents air-holes in the liner which are pre erablystaggered in relation to the air-holes 10 on the exterior sides of thebox. 14 is a flap which will fit into 14: of the liner and prevent thebox from unfoldin The. flap 14 after being fitted into 14: 1s retainedin place by means of mucilage. or by other means.

The preferred arrangement of ventilating holes is as follows. Theyshould be equally spaced from each other and from the cornets of the boxand on only two opposite It may also be desirable readily made bystaples glue or paste may be used.- In Fig. 3 the sides of the box.- Theinner elliptical strip must be cut for ventilation in the same fashion.

In Fig. 1 the the body of'the points 11 to 12. is the liner to the rightof 12 and can, therefore, all be stamped out or cut out in one piece. InFig. 1 the box will be.rectanguhorizontal cross section, so that whenppper material comprising ox itself that is between lar 1n the liner isplaced within the box it will assume an ell1 tical form as shown in Fig.2.

When the ox is folded the liner will touch the part 5 for a shortdistance but it will not touch the box in any other point except at thecenter'of the sides thereof, so that any material which will be packedin the box will be exposed to only one edge of paper in the liner andwill be separated from the exterior wall of the box at all places by theliner. The .liner 9 is made long enough, so that it will overlap aportion of itself and form a completely elliptical liner. Thisoverlapping portion being unsecured will permit a change in the lengthof the perimeter or circumference of the liner. This will have the veryimportant advantage of permitting a change-in the circumference orperimeter of the box to accommodate distortion of the external square orrectangular box and in this manner a substantially constant volume willbe maintained within the liner so as to.prevent crushing of thevegetables contained therein.

Fig. 3 represents certain changes which can be made in the box ofFig. 1. When it is desired to make the'external box portion of one papermaterial such as cardboard and the liner of another material such ascorrugated paper, the liner and the exterior box portion will be stampedout or cut out separately and then later stapled together of the samematerial as' at 13 in'the manner indicated; instead of other means ofattachment, such as air-holes on the exterior of the box aregreatlydecreased in number and an alternative method of admitting air tothe interior within the liner is shown at 10 2 and 2 are shown slightlyelongated with flaps b and c on the outside thereof, so that there willin this manner be able to, form lids for thebottom and top of the boxwhen folded.

Although throughout the specification I have described the use of acircular or elliptical liner, nevertheless, it .is possible to use inplace of such octagonal. or other horizontal cross section which willperform the functions of the circularor elliptical liner and which maybe considered as completely rounded liners. When the. rimary purpose isto prevent the vegetable rom touchingthe exterior walls of the box andit is not so important to avoid the presence of sharp corners, even aaliner a liner of hexagonal,

triangular liner could be used. These liners could be readily made byscoring the portion which has been stamped out to form a liner in thedesired places. I

The exterior of the box instead of being of rectangular or square crosssection could also be of other cross sections such as octagonal,hexagonal or-even triangular, but the box of square or of rectangularcross section is much preferred since it is better for packing andshipping purposes and is much stronger and can be readily'handled. If abox whose exterior has a circular cross sectiontis desired the interiorcross section could be made square or of some other shape so as toprevent contact between the vegetable and the exterior wall of the box,

' butthe preferred form of my invention consists in the use of a box,the exterior of which is square or rectangular and the interior liner ofwhich is circular or elliptical.

Having described my invention what I claim is: v

1. A flat paper form which can be folded into a rectangular box forpacking materials Which comprises a portion which can be folded into anexterior and another portion integrally attached thereto which whenfolded will form a completely rounded liner completely encircling thecontents of the box sa'id liner being of such construction that it willoverlap a portion of itself, said overlapping portion being unsecured.

2.- A paper box of rectangular horizontal cross section containing acompletely rounded linerwhich is made by folding a flat paper form, inWhichpaper form is contained a portion, which forms a one piece liner,said liner portion being integrally attion, said box being formed byfolding a flat piece of paper material which piece of paper materialwill contain forms for the exterior part of the box and the liner, saidliner form being integrally attached to the form for the external partsaid liner preventing any contact between material packed within it andthe exterior side walls, said liner being of such construction that itwill overlap a portion of itself, said overlapping portion beingunsecured. v p

4. A flat paper blank which can be folded into a box of rectangularhorizontal cross section containing a completely rounded liner,comprising portions for the four side walls. and incontinuation of theportion for the side wall an integral portion for the liner and flapsattached to each side wall which will fold over and make a top andbottom for the box, struction that it will overlap a portion of itself,said overlapping portion being unsecured.

In testimony whereof I afiix my signature.
